Resistive Heating Induced by Streaming Cosmic Rays Around a Galaxy in the Early Universe
Shota L. Yokoyama, Yutaka Ohira
It is expected that cosmic rays (CRs) escape from high-redshift galaxies at redshift because CRs are accelerated by supernova remnants of the first stars. Alt…

Biermann Battery Powered by Resistive Heating Induced by Cosmic Ray Streaming
Shota L. Yokoyama, Yutaka Ohira
It is recently proposed that cosmic rays generate a seed magnetic field in the early universe. In this paper, we propose another generation mechanism of magnetic fields by cosmic r…

Particle acceleration in a shock wave propagating to an inhomogeneous medium
Shota L. Yokoyama, Yutaka Ohira
We investigate effects of upstream density fluctuations on the diffusive shock acceleration by Monte Carlo simulations. The simulations show that particles are reaccelerated in the…
